EXTENDROM_SIGNING_PATCHES = true
This adds support for
- increased key size within system/update_engine (i.e. Android Settings -> Updater), allowing to verify OTA packages signatures up to sha256 + 8192bit
- increased key and hash sizes within recovery (only!*) allowing to verify ADB sideload zip signatures up to sha512 + 8192bit
*) Note: if you plan to use the sha512 hash algorithm to sign your OTA packages you can apply them by ADB sideload within recovery only. That means OTA updates within Android will fail until system/update_engine has been patched, too (which is not part of extendrom - atm).
